FRAME FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented June 15, 1909.

To all whom it may concern:

Be it known that I, CHARLES SCHMIDT, a citizen of France, residing at Detroit, in the county `Df'VVayne, State of Michigan, have invented certain new and useful-Improve ,.nfents in Frames for Motor-Vehicles, of which the following is a S ecification.

This invention re ates to improvements in motor vehlcle frames and 1t conslsts 1n a frame 1n which each of the slde bars has a Areverse-curve or offset and a reinforce coin- .gReferring to the drawing the, frame consists of side bars 10, end bars 11 and transverse bars or braces 12. The side and end bars are of channel-section, having upper flanges 13 and lower flanges 14. They have preferably a uniform depth at the middle orticn and taper toward the ends, as shown 1n Fig. 2, the lower flange 14 being referably inclined upward while the up er ange 13 is horizontal. ,Toward oneen of the frame the side bars are offset, being curved inward at 15 and outward at 16, the general contourr being that of a reverse curve and the forward portion 17 being parallel with the rear por. tion 18.` At the offset portion the upperV and lower flanges of the side bars are increased in width as shown at 19 and the offset portion is reinforced by a corresponding piece or reinforce 20. The reinforce is preferably of channel-section of such size as to fit snugly Within the side bar roper and having its flanges enlarged at t e middle as shown at 21, to correspond with the enlargement 19 of the side bar flanges. The reinforce is suitably connected to the Side bar byrivets. A frame thus constructed is practicall of uniform strength throughout its lengt and is not weakened by the. offset or reversely curved outline which is necessary to adapt it to the vehicle body.

Having described my invention what I claim and desire to secure by Letters Patent is,

1. A motor vehicle frame having its Side bars reversely curved or offset as shown, each side bar having parallel front and rear portions and having upper and lower flanges which are wider at the offset portion than at the front and rear portions.

2. A motor vehiclel framecomprisin end bars and side bars having upper and Tower flanges, the side bars having intermediate offset or reversely curved portions, and channeled reinforcing pieces secured to said side bars at the offset ortions and between the upper and lower anges thereof, the flanges bemg'wider at the offset portions of the s1de.

bars than elsewhere, for the purpose set forth.

3. A motor vehicle frame comprising channeled side bars, the lower flanges of said side bars being inclined upwardly at each end and the up r flanges of said side bars being substantla lyl horizontal, said side bars having offset portions intermediate their ends, and reinforcing pieces secured within the flanges of the side bars at the offset 'portionsglthe flanges being wider at the offset ortions of the side bars than elsewhere, for t e purpose set forth.

In testimony whereof I have signed \my name to this specification in the presence of two subscribing witnesses.

CHARLES SCHMIDT.
